Re: top displaying 50% si time and 50% idle on idle machine

Cpu(s): 0.0% us, 0.0% sy, 0.0% ni, 50.0% id, 0.0%
wa, 0.0% hi, 50.0%si

BTW what means si? (interrupt service time? google
didn't find anything)

'soft interrupt' probably. try disconnecting network.

The cause has been found. The timer of that machine is seriously
broken, 1 second is approximately 500ms long.
It is a HP DL360 G4 and I configured the kernel without ACPI or
similar. Maybe there are some strange BIOS power management schemes
active. I will look deeper into the problem and report back.
A broken timer is _very_ strange to me (I didn't encounter that in the
last 12 years w/ custom kernels).

Cheers,
M.
